Box-sesame nnvron.

Application 'filed October 13, 1925. Serial Ito/62,824.

This invention relates to box sealin devices and has relation more particular y to a device of this kind especially designed and adapted for use in closing the ends of cartons, and it is an object of the invent on to provide a device of this kind WhlCh in its structure comprises no levers, eccentrics or the like.

Another object of the inventlon 1s to provide a device of this kind 'comprlslng a platform and a box or carton holder pivotally supported thereby and which, when swung below the platform, coacts with such platform to impose suflicient tension upon the closed end flaps of a carton or the l ke upon the holder to assure requisite eifective gluing of said flaps to close an end of the carton.

A further object of the invention is to provide a device of thiskind wherein the holder or holders comprised therein, when not in use, are substantially confined below the platform and thus permitting the platform to be emplo ed without hindrance or obstruction forot er purposes, such as gluing, stencil work and the'like.

The invention consists in the details ofv important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more full set forth.

T e novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a View in elevation lllustrating a box sealing device constructed 1n accordance with an embodiment of my inven tion' Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1;

Figure 3 is a fragmentary view in per; spective of a holder showing a carton initially applied; U

Figure 4 is a view similar toF-igure 3 showing the flaps at an end of the carton partly folded;

Fi ure 6 is a sectional view taken sub-' stan t1ally on the line 66 of Fi Figure 7 is a view in of the holders unapplied.

As disclosed in the accompanying drawings, P denotes a platform of desired configuration and dimensions but herein disclosed as of a material length and rectangular in design, said platform being maintained in desired elevation by the supportlng legs 1 coacting in a conventional manner with the longitudinal marginal portions thereof. 1

The legs 1 at one side of the platformP are transversely ali ned with the legs at the opposite side an the lower portions of each pair of transversely aligned legs 1 are tied or connected by the cross members or beams 2. Disposed through the opposite end portions of t ese cross members or beams 2 and at desired points inwardly of the legs 1 are the bars or pi s 3 extending longitudinally of the platf dim P and substantially the entire length thereof, said rods or pipes 3 providing mountings for the holders H.

Each of the holders H comfprises atopor table 4 of a size and con guration to conform to the interior dimenslons of the end of a carton to be closed and de ending from the sides of said top or ta 1e 4, and at right angles thereto are theside perspectlve of one the top or table 4. The lower portions of 4 the arms 6 are freely mounted on a rod or pipe 3 whereby the holder is supported for swinging movement in a vertical direction, the mountings for the holder being so positioned of the arms that the top or table 4 closely approaches the under surface of the platform P when the holder is in upright vertical position, such space a being substantially equal to the overlying or overlapping end flaps F of-a carton C to be glued in closed assembly. Furthermore, it is to be noted that the rod or pipe 3 is positioned inwardly from the ad acent longitudinal margin of the platform P to'have the for- .end is removed therefrom.
